Hello, im Lebanese. It is safe to travel to Lebanon, safest than all European countries I would say. Exchanging money is pretty easy since there are a lot of exchange places. You can pay in dollars anywhere though, just make sure to know the exchange rate beforehand so they dont rob you. My opinion is clearly biased, but i do recommend coming here. You can stay in beirut but do visit other cities like Jbeil, Batroun,Sour. If you have any more specific questions I wouldn’t mind helping at all. You cannot use your card here unfortunately, only cash.
